Thats the idea... perhaps a few other places...
After I finish my BB's I need to build more cruisers, support ships, tankers, etc...

I swear: someone with an inkling to do that sort of work for a while could make a killing building a standard tanker design for the rest of the world.
Something like this?

Good concept
IMO,I increase slightly armament to repulse a DD atack (120mm in place of 75mm)
Good speed to be with a BBs squadron.
They could be use also as auxiliary cruiser or raider
& with that gun boat collier, GBC , you must not pay the 5$ surtaxe !!!

Re: Oiler/Collier:
I still have no idea what a good speed for such a ship is. It's my instinct that top speed doesn't matter as much, since I'd expect one would get sent far away from battle should one appear likely. Crusing speed probably does matter though, especially once underway refueling comes along.
Poking around at US examples, what sources I can find say the Cimarron class of WW2 only did something between 16 and 19 knots. This was with 30,400 SHP, but they were also over 24,000t full load.
What examples I can find from WW1 of US Colliers and Oilers seemed to be quite a bit slower.
Of course, the US is hardly the only set of examples out there, and later I may try to find the speed for other navy's ships...
I am going for max speed of 20 knots... odds are it is too fast... especially looking at WW2 convoy speeds but I want something able to keep up with the battleline...
Below is a small collier / tanker... Figure build 4 of the larger ones and 12 of the smaller ones... half for the Pacific and half for the Atlantic. 4.5 BP's for the large ones and 6.3 BP's for the smaller.

Good seaboat, rides out heavy weather easily
Four large and twelve small sounds like overkill, really.
2 A-C/TL & 6 A-C/TS in the Atlantic and in the Pacific. As I have to support to locations. Also in the event of a war I need to consider yard time and or war losses.
Yes for the raw size of the Iberian navy 4 & 12 is too big but I need to be able to support things around the globe. Also some will be tankers and some will colliars so... Odds are half and half...
Michael
Or Iberia could simplify logistics by making the Far East/Indian Ocean fleet oil firing.
The European Fleet would make more sense; the Philippines have large coal fields. Oil isn't an a real choice from the obvious source in the area.
